  "abstract": "A foam-pad vacuum gripping tool comprising one mounting flange, four foam pads, one vacuum pump, one manifold, one pressure sensor, one contact detector and one vent valve. When the foam pads reach the workpiece, the foam pads are evacuated by the vacuum pump. Before the workpiece reaches the set-down position, the vacuum circuit is vented by the vent valve while the workpiece is above the receiving surface. The arrangement is a proposed configuration composed from a typed library of mechanism blocks derived from published patents; it has not been constructed.",
